pythonDeprecatePythonPath experiment causes interpreter in .venv to not be used, even when selected manually

See original GitHub issue

Environment data

  • VS Code version: 1.60.1
  • Extension version (available under the Extensions sidebar): v2021.9.1230869389
  • OS and version: Manjaro 21.1.3
  • Python version (& distribution if applicable, e.g. Anaconda): cpython
  • Type of virtual environment used (N/A | venv | virtualenv | conda | …): venv
  • Value of the python.languageServer setting: Pylance

Expected behaviour

The interpreter in .venv should be found and shown as an option. Also, if I enter the path manually or select the interpreter via the file browser, that should be used.

Actual behaviour

The interpreter in .venv is not selectable, except when setting the "python.defaultInterpreterPath": ".venv/bin/python".

If I select that or enter the path manually or select the path via the file browser, the interpreter isn’t actually selected and the button in the bottom bar still shows “Select Python Interpreter”, despite the “Select interpreter” dialog showing “Current: ./.venv/bin/python”.

Steps to reproduce:

  1. Create a venv in .venv
  2. Try to select the interpreter .venv/bin/python

I could not reproduce this issue myself anymore, seems like it was something transient. Sorry for not responding earlier.

Also, does the issue only happen when in pythonDeprecatePythonPath experiment, i.e does adding the following User setting helps?

  "python.experiments.optOutFrom": ["pythonDeprecatePythonPath"],
  "python.experiments.optInto": ["pythonDiscoveryModuleWithoutWatcher"],
